zebra daemon collects information from other daemons and handles static routing tables accordingly.
The other daemons are known as bgpd, ospfd, ospf6d, ripd, and ripngd.
Daemons are enabled by editing the /etc/quagga/daemons file and creating the appropriate
configuration file in /etc/quagga/; this configuration file must be named after the daemon,
with a .conf extension, and belong to the quagga user and the quaggavty group, in order for
the /etc/init.d/quagga script to invoke the daemon.
The configuration of each of these daemons requires knowledge of the routing protocol in question.
These protocols cannot be described in detail here, but the quagga-doc provides ample explanation
in the form of an info file. The same contents may be more easily browsed as HTML
on the Quagga website:

In addition, the syntax is very close to a standard router's configuration interface, and network
administrators will adapt quickly to quagga.
IN PRACTICE
OPSF, BGP or RIP?
OSPF is generally the best protocol to use for dynamic routing on private networks,
but BGP is more common for Internet-wide routing. RIP is rather ancient,
and hardly used anymore.
10.5. IPv6
IPv6, successor to IPv4, is a new version of the IP protocol designed to fix its flaws, most notably
the scarcity of available IP addresses. This protocol handles the network layer; its purpose is to
provide a way to address machines, to convey data to their intended destination, and to handle
data fragmentation if needed (in other words, to split packets into chunks with a size that depends
on the network links to be used on the path and to reassemble the chunks in their proper
order on arrival).
Debian kernels include IPv6 handling in the core kernel (which was not always the case; the ipv6
module used to be optional). Basic tools such as ping and traceroute have their IPv6 equivalents
in ping6 and traceroute6, available respectively in the iputils-ping and iputils-tracepath
packages.
The IPv6 network is configured similarly to IPv4, in /etc/network/interfaces. But if you want
that network to be globally available, you must ensure that you have an IPv6-capable router
relaying traffic to the global IPv6 network.
